Engineering Dissipative Quasicrystals
Tianyu Li, Yong-Sheng Zhang, Wei Yi
We discuss the systematic engineering of quasicrystals in open quantum systems where quasiperiodicity is introduced through purely dissipative processes. While the resulting short-…
Synthetic topology and Floquet dynamic quantum phase transition in a periodically driven Raman lattice
De-Huan Cai, Wei Yi
Stimulated by the recent progress in engineering topological band structures in cold atomic gases, we study the dynamic topological phenomena for atoms loaded in a periodically dri…
Simulating non-Hermitian quasicrystals with single-photon quantum walks
Quan Lin, Tianyu Li, Lei Xiao +3
Non-Hermiticity significantly enriches the properties of topological models, leading to exotic features such as the non-Hermitian skin effects and non-Bloch bulk-boundary correspon…
Engineering Non-Hermitian Skin Effect with Band Topology in Ultracold Gases
Lihong Zhou, Haowei Li, Wei Yi +1
Non-Hermitian skin effect(NHSE) describes a unique non-Hermitian phenomenon that all eigen-modes are localized near the boundary, and has profound impact on a wide range of bulk pr…
Observation of non-Hermitian topological Anderson insulator in quantum dynamics
Quan Lin, Tianyu Li, Lei Xiao +3
Disorder and non-Hermiticity dramatically impact the topological and localization properties of a quantum system, giving rise to intriguing quantum states of matter. The rich inter…
Detecting non-Bloch topological invariants in quantum dynamics
Kunkun Wang, Tianyu Li, Lei Xiao +3
Non-Bloch topological invariants preserve the bulk-boundary correspondence in non-Hermitian topological systems, and are a key concept in the contemporary study of non-Hermitian to…
